I would like to ask about the dress code: royal touch. I would like to know how a man should be dressed if he would like to follow the code.
From one point of view, it is definitely an off-topic since it is not a question about grammar or language usage.
On the other hand it can be considered as a question about a definition(explanation) of an English word/phrase which should be suitable for EL&U. What is more, I believe that people here can know about this matter more then on the other sites.
So are the questions in this sense appropriate in EL&U? If no, where should I ask about this particular issue?
